Claims.

This invention relates to apparatus for filling seat cushions, and othersimilar articles of an elastic nature, with fibrous, fiocculent paddingmaterial to produce an attractive, dilated appear- 5 ance, and comfortin their use, with particular reference to cushions in which metallicsprings are incorporated.

While the invention is sufiiciently broad to be used in stuffingmattresses, bolsters, pillows and seats of all kinds that embody elasticor resilient material enclosed in an inner casing, it is specificallyadapted for use in the construction of seat cushions having edgeextensions, as for instance to partially enclose the arms of a chair orpro: trude below its back.

To merely fill such projecting portions of a cushion with padding isunsatisfactory as, after a period of time, the material becomescondensed and the pristine appearance of the cushion suffers to thedetriment of the article with which it is associated.

It is therefore an object of the invention to provide an apparatus inwhich such lateral extensions of the cushion are provided with meanswhich permanently maintain them in their prime, original condition,irrespective of wear or the lapse of time.

A further feature is in the provision of an attachment for cushionfilling machines adapted to introduce the usual type of cushion springsinto such marginal extensions as may be desired, the device beingadjustable to suit varying shapes, sizes and conditions.

Another purpose is to produce a device easy to operate in an effectivemanner, inexpensive in construction, and readily applicable to existingmachines.

These useful purposes are accomplished by the novel and practicalconstruction, combination 40 and arrangement of simple parts hereinafterdescribed and illustrated in the accompanying drawings, constituting animportant component of this disclosure, and in which:

Figure 1 is a partial side elevational view of a conventional type ofcushion filling machine showing an embodiment of the invention asapplied in operative position. 1

Figure 2 is a top plan View thereof.

Figure 3 is a front end elevational view of the same.

Figure 4 is a front end view showing the filling container sides widelyspaced and the cover plates partially raised.

Figure 5 is a side elevational view thereof. Figure 6 is a view similarto Figure 4 but showing the side walls as moved laterally towards eachother and the cover plates closed.

Figure 7 is a side view of Figure 6.

Figure 8 is an end view showing the parts as in Figure 6 and indicatingin broken lines the cushion extension elements.

Figure 9 is a side view of Figure 8, showing the side walls removedrearwardly and held in such position.

Figure 10 is a longitudinal sectional View showing the initial positionof the container and spring transfer plates.

Figure 11 is a like view of the same parts when in position to permitexpansion of the cushion extensions.

Referring in greater detail to the drawings, the hollow base l5 of thefilling machine has rotatably mounted in it a sprocket wheel l6 drivinga chain carrying series of pusher bars I! engagedwith a plunger l8,guided by rolls I9.

A filling container, generally designated by the numeral 20 is attachedto the upper surface of the base by a rigid plate 2| extending over thefront of the machine.

This box or container comprises a bottom formed by two horizontal plates22-23 rigidly attached at their outer edges to upright side plates24-25, their height being essentially equivalent to the thickness ofthe'article to be stuffed.

Hinges 26-21, at the upper edges of the upright sides, connect foldablecover plates 28-29 in overlapping slidable relation.

On opposite sides of the base l5, are rigid outreaching brackets 30-3lin which are journalled the ends of a screw having right and left handportions respectively 32-33, the former provided with a hand-wheel 34for manual operation.

The right hand portion 32 of the screw engages the threads in a lug 36at the front side of the machine and the left hand portion similarlyengages a lug 31 at the opposite side.

These lugs are firmly attached to the bottoms 22-23 of the container 20in such manner that the side walls 24-25 may be positively moveddifferent distances apart by turning the handwheel 34, the cover plates28-29 sliding on each other laterally and the bottom plates 22-23movable on the plate 2| attached to the top of the column base [5.

A pair of upper and lower grooved horizontal guides, respectively 38-39are carried by the side walls 24-25 on their longitudinal edges andslidably engaged therein are plates 40-4! of auxiliary casing sidesadapted to transfer coiled 55 metallic springs from within to the innerenveloping member of a cushion.

The front ends of these plates are normally in register with the outerends of the container side walls, being pushed outwardly by anypreferred means, as for instance springs 42 and are provided with pins43 engageable by catches 44 pivoted at the rear of the machine, as onthe plates 2425.

The fulcrum point 45 of the catches may be changed to present more orless space outwardly beyond the front ends of the side walls 2&-25 toaccommodate lateral cushion extensions of varying width.

To perform the stufiing operation, the padding or spring filling, asrepresented in broken lines, is inserted in the container, between'thewalls 24, (Figure 10) and the plates 2829 closed thereover. The cushionor article cover, not shown, is drawn over the front end of the closedstructure, the bottom of the cover being disposed against the open endof the container, in 2. marner well known in the art. The hand wheel 34is finally operated for fine adjustment to draw the cushion coversufiiciently taut.

As shown in Figure 11, the plates 41!, 4| are retracted against theaction of the springs 48, by the manipulating knobs 43 (Figures 1 and2), and are held retracted by the members 44. On retraction of saidplates, causing opposed lateral openings in the container, the oppositeends of a front transverse coil spring, encased in padding, such ashereinbefore stated and represented in broken lines, Figure 11, areurged outwardly into suitable pockets of the aforesaid cover.

The sprocket wheel l6, driving a chain, carrying members IT in wellknown manner, then causes the pusher I8 to eject the spring filling,with the cushion cover embraced thereon. The diameter of the transversespring, which is also padded across its length between said ends, isless than the depth of the vertical coil springs, so that the latterhave considerable normal yielding movement before reaching a depth equalto the diameter.

After the cushion has been stuffed, depression of the foot lever 47,acting through the flexible connection d8, releases the catch,permitting return of the plates 404I to their initial position.

From the foregoing it will be seen that a simple device for this purposehas been disclosed in the preferred form of the embodiment, but it isnot desired to restrict the details to the exact construction shown, itbeing obvious that changes,

not involving the exercise of invention, may be made without conflictingwith the scope of the appended claims.

Having thus described the invention, what is claimed as new and soughtto secure by Letters Patent, is:

1. In combination with a cushion filling machine having an open endedrectangular container provided with laterally movable side Walls, and aplunger operable therein, auxiliary plates adjustable lengthwise on saidside walls and normally extending therebeyond at the front between thecover and bottoms of the container, latches to retain said plates whenadjusted rearwardly thereby to present lateral openings at the front,and means to simultaneously release said latches.

2. In a cushion filling machine, an open ended rectangular box havinginner and outer pairs of side walls arranged in juxtaposition andrelatively slidable lengthwise, both pairs movable in unison laterally,and upper and lower plates movable conjunc-tively with said inner wallsand extending outwardly beyond said inner side walls at one end whereby,upon moving said outer side walls in a direction opposite said extendingplates opposed lateral openings are presented.

3. A machine for transferring a spring filling to a cover comprisingopposed top and bottom walls and opposed relatively short side walls,guides carried by said side walls, and slide plates mounted on saidguides closely against said walls, whereby the latter may be selectivelylengthened.

l. A machine having a rectangular casing for displacably receiving aspring filling for a cushion cover, said casing including an open frontend and having relatively short side walls, there being temporarylateral openings at said walls, guides mounted on said walls, slideplates carried by said guides for selectively closing the openings, andmeans urging the slide plates into closing position.

5. A machine for transferring to a cushion cover a filling havingextensible lateral spring projections, comprising in combination, alaterally adjustable casing having an open front end and including shortside walls, there being temporary side openings at the ends of saidwalls, guide means carried by said walls, slidable members mounted onsaid means and removably closing the openings so as to restrain theprojections, and means whereby to slide said members for allowing saidprojections to automatically spring through the openings.
